Lets see...I've seen some solid rainstorms in it at the Wind River Range. Rained a little at least every day. A couple days saw some good downpours. The tent performed well; only thing is after the wetting of the rain fly, you will need to tighten up the guy lines. That is critical to maintain good ventilation in this tent and to keep the interior dry. Although it did get windy in the Winds as well, we camped in the trees so the wind was never a real factor. I would say I might be a little leary of taking the thing into really strong winds; the material is thin. I have had it up on the White Mountain Crest (California), however I carried a strong tarp with me to stake down over the tent in the up wind direction just in case. As it turned out, the winds were not too bad where I found campsites. I like the tent. but if you were going into and area known for strong winds at the time of year you are going I would probably look for something beefier.
